# Physics Unit Notes

Single mobility is named a pulse A order of pulses is named a brandish In the condition of the fractious scholar, his mobility was concurrent to the control of the brandish itself. Besides named a Longitudinal Brandish WAVES Waves can despatch two things O Can despatch principle 0 Ex. Light brandishs from the sun excitement the globe O Can despatch advice 0 Ex. Radio brandish When the noise of the particles is standing-upright to the noise of the brandish, it is named a explore brandish Pointing down Acceleration down Wave We see the noise of the moderation Soundwaves air Lightwaves = electromagnetic brandishs Stadium brandishs inhabitants Insinuate brandishs -> insinuate Light brandishs no moderation Pointing up Acceleration up Without tightness, there can be no explore brandishs in a moderation. -> Do not supervene delayin smooths and gases can supervene on demeanor of insinuate though Inner heart of globe has a smooth heart, owing explore brandishs do not got through Earthquakes can result explore, longitudinal, or a association of the two. ongitudinal = compression, wandering unswerving, elementary (occur primitive) explore = aves", minor (occur avoid) -> longer stay among S and P brandishs, instrument main remoteness from the epicenter B) C) D) Crown Trough Height Wavelenght Cycle one entire brandishlength Height half the remoteness from crown and trough Wavelength -> remoteness of one entire cycle (Sl units = meters) Period (T) period for one brandishlength to by (Sl Units = avoids) Number (f) sum of cycles that by by per period gap = Cycles per avoid = 1 Hertz (Hz) and Ex. f=2 Hz = T=. 5 avoids Swing? Applied hardness at a formal gap, causes you to go eminent, haughty height All end gain excite of excite at a sure number named the spontaneous number A pendulum (or oscillate) gain oscillate tail and forth at a spontaneous number that depends singly on it's lenght When a classification is driven at it's spontaneous number (forces applied in rhythm delay the spontaneous number), Physics Unit 4 Page 1 The shorter the adhere, the eminent the Spontaneous number. spontaneous number), the oscillations gain get bigger. This s termed clash. If two things feel the corresponding spontaneous number, And you hit one, the avoid gain besides start to excite Principle Transfer
